Title: Sensing matrices for radioactivity-distribution detectors
IPC: G01T1/164
Filed: 1972-12-13
Abstract: 1406685 Radiation detectors BAIRDATOMIC Inc 13 Dec 1972 57614/72 Heading G1A [Also in Division H4] The distribution of radio-activity over an area is measured using a sensor comprising a two dimensional array of a certain number of scintillator elements coupled by light guides to a smaller number of photo-detectors in such a way that a scintillation in an element produces a signal from a unique combination of one or more of the detectors. As shown, Fig.1, the sensor comprises an array of scintillator elements arranged in alternately staggered rows making up a layer 28 light from which is conducted by light guides 30 having square ends transforming to cylindrical portions which terminate at individual detectors 14. The square ends of the light guides are larger than the scintillator elements and are positioned so that they cover the whole of one scintillator element and half of each of six surrounding elements. Each scintillator element is therefore coupled to a single one of the detectors or to a unique pair of the detectors. The outputs of the detectors are analysed to select pulses within a specific amplitude range or energy window and these pulses are passed by an address register 24 to a location in a memory 26 corresponding to the co-ordinates of the originating scintillator element. The outputs of the detectors are also applied to low level discriminators 18 connected to logic circuitry 20 which determines whether or not scintillations occurred in two or more elements simultaneously and produces a corresponding reject or accept signal which controls address register 24 so that false outputs due to simultaneous scintillations are not recorded, A suitable pattern for the arrangement of square scintillator elements and light guide ends is given, Fig. 4 (not shown) and this may be modified by making the ends of the light guides hexagonal, Fig. 6 (not shown). Either arrangement may utilize a plurality of first light guides, having pick-up ends as previously described, which are themselves coupled to further larger light guide ends which conduct the scintillations to the detectors, Figs. 5 and 7 (not shown). In this case each larger light guide covers half the area of four adjacent intermediate waveguides and is rectangular or trapezoidal in shape as appropriate. The scintillator elements may be of T1 activated Nal crystals or Cs crystals and the light guides may be of an acrylic resin such as methyl methacrylate, of clear epoxy resin, or of glass.

Abstract: 1394064 Retractive switches NATIONAL RESEARCH DEVELOPMENT CORP 21 Dec 1972 [21 Dec 1971] 59469/71 Heading H1N A switch unit, suitable for use under a mat and of the kind which breaks a circuit when stepped on, comprises a metalleafspring 1 which in the unstressed condition has a bowed portion 2, a metal stud having a shank 6 which passes freely through a hole 3 in the bowed portion 2, a head 7 on the convex side of the bowed portion and larger than the hole 3, and restraining means co-operating with the stud and the ends of the bowed portion so that the bowed portion is held under stress by the head of the stud which thereby makes electrical contact with the leaf spring but is otherwise insulated therefrom. As shown in Fig. 1, a rigid insulating base 4 provides the restraining means, but in the embodiment of Fig. 3 a second leaf spring 10 acts against a second head 7a of the stud, which may be fixed in the insulating base 4 or pass freely through a hole 12, as shown. Several switch units may be assembled in series and enclosed in a p.v.c. envelope (30, Fig. 4, not shown). The insulating base member may be a flexible sheet (4a) of p.v.c. and may be heat sealed to the envelope (30). In a modification (Figs. 7 and 8, not shown) an even more flexible arrangement is disclosed wherein the base member is replaced by individual discs (45) of p.v.c. This allows the assembly to be formed into various shapes by pivoting about the studs, and the discs (45) may then be spot-welded to a plastics envelope sealing the whole switch. The springs and studs are of stainless steel, spring steel, or beryllium copper, and may be gold or silver plated at the contact areas.

Title: Phototubes
IPC: G01T1/164
Filed: 1970-12-30
Abstract: 1320540 Detecting position of X-rays or gamma-rays ELSCINT Ltd 30 Dec 1970 [7 Jan 1970] 61842/70 Heading G4H [Also in Divisions H1 and H4] An array of conductors is juxtaposed to a photo-cathode so that the cathode can be scanned by selective suppression of its emission. A photo-multiplier tube so modified may be used to locate the position of a light flash produced in a crystal by a gamma-ray or an X-ray. The crystal may be spaced from the photocathode (Fig. 1, not shown) so that the spread of the light is limited by internal reflection, or alternatively a matrix of crystals may be located on the end window of the tube with no air gap so that only one crystal is excited by an incident ray and the light from that crystal reaches only a small area of the cathode. In Fig. 4 the photo-emissive surface 13<SP>1</SP> on a glass substrate 12 covers an array of conductive strips 13 separated from a further array 15 by a glass layer 14; the outer glass layer 16 is covered with a reflecting matrix 17 which ensures that incident light is not diffused but is optically piped through the window. In operation the strips are pulsed in sequence, preferably a sequence which gives successive approximations to the position. If there are 32 strips, numbers 1-16 may be pulsed in a first time interval, numbers 1-7 and 17-24 (i.e. the first halves of each of the space intervals identified by the first pulse) in a second time interval, and so on for five pulses; then the orthogonal strips are pulsed in similar fashion. When a strip adjacent an incident light flash is pulsed positively, the output current of the tube is depressed (Figs. 3a and 3b, not shown), and this reduction is detected by a discriminator circuit (Fig. 3e, not shown) synchronized with the pulsing. The discrimination is based on total current per time interval, and the discrimination level comprises a D.C. component designed to give equal probability to false positive and negative indications and a component variable in accordance with the energy of the incident particle as measured by the initial rise of the input pulse. To avoid errors due to the bad conductivity of the cathode, its surface may be coated with discrete conductive areas corresponding to the detection areas of the arrays of conductors. The continuous conductors 13 and 15 shown in Fig. 4 may be replaced by discrete conductive meshes each connected by diodes to a pair of X and Y co-ordinate wires, possibly arranged externally (Fig. 6, not shown). In another application the photo-cathode can be scanned to provide a television picture.
